Description
Technical field this utility model relates to a kind of instructional device, especially one and utilizes gravity simulation load to add
The hydraulic pressure actual training device carried.
The hydraulic pressure actual training device that background technology uses in the market, is cannot to realize the loading of hydraulic system in fact mostly
Test.Only having a small amount of scientific experiment utilizes sensor to realize the equipment of simulation loading.From practical experience, both the above situation is all
There is corresponding weak point:
1, cannot be carried out the hydraulic pressure actual training device of loading experiment, it is difficult to meet teaching request, hydraulic system stress is ground
Study carefully analysis very inconvenient.
2, the hydraulic pressure actual training device using sensor to be simulated, has dependence, and component structure is complicated power supply in work,
Rapid wear during real training, cost is higher simultaneously, it is difficult to universal use.
3, the hydraulic pressure actual training device using sensor to be simulated, uses operation easy not, is unfavorable for that student intuitively manages
Solve.
Summary of the invention this utility model is for the problem in the presence of above-mentioned prior art, and research design is a kind of novel
Can the hydraulic pressure actual training device that loads of fictitious load, for the problem that solves to deposit in prior art.
This utility model is made up of hydraulic circuit, hydraulic cylinder and analogue loading device, and hydraulic circuit passes through hydraulic line
Being connected with hydraulic cylinder, the piston rod of hydraulic cylinder is threadeded with analogue loading device；Described analogue loading device pallet, fixing
Bar and 3 detachable counterweight compositions.The threaded fixing bar of upper surface of described pallet, the threaded hydraulic cylinder of its lower surface is lived
Stopper rod.Counterbalance mass is respectively 0.5kg, 1kg, 2kg.
After using said structure, self assemble hydraulic circuit can be needed according to teaching, realize different system with this and control back
Road；According to the requirement of education experiment, flexible repeated loading counterweight, it is achieved hydraulic loaded is tested.
The beneficial effects of the utility model:
1, have novel structure, easy and simple to handle, motility is high, safe and reliable, be easy to the advantages such as record in control.
2, have employed the mode of simulation loading due to this utility model, solve real load in experimentation and load tired
Difficult, it is difficult to realize, it is difficult to the problem of tolerance；
3, load owing to this utility model have employed weight type, independent assortment can be passed through, it is achieved loading simulation flexibly, it is simple to
Data acquisition and experimental record；
4, using gravity simulation to load due to this utility model, the loading procedure making experiment is simple, safe and reliable, just
In operation.
Description of drawings 1 is front view of the present utility model.
Fig. 2 is this utility model analogue loading device internal structure axonometric chart.
Fig. 3 is the axonometric chart of this utility model load device counterweight.
Description of reference numerals: 1, hydraulic circuit, 2, hydraulic cylinder, 3, analogue loading device, 4, hydraulic pump, 5, overflow valve, 6,
Two-position four-way solenoid directional control valve, 7, Pressure gauge, 8, hydraulic line, 9, pallet, 10, fixing bar, 11, counterweight.
Detailed description of the invention as shown in Figure 1-Figure 3, a kind of can fictitious load load hydraulic pressure actual training device in, by liquid
Pushing back road 1, hydraulic cylinder 2 and analogue loading device 3 to be formed, hydraulic circuit is connected with hydraulic cylinder by hydraulic line 8, hydraulic cylinder
Piston rod threaded with analogue loading device；Described analogue loading device pallet 9, fixing bar 10 and three are detachable
Counterweight 11 forms.The threaded fixing bar of upper surface of described pallet, the threaded hydraulic cylinder piston rod of its lower surface.Counterweight matter
Amount is respectively 0.5kg, 1kg, 2kg.
During actual training operation, can need self assemble hydraulic circuit according to teaching, usual hydraulic circuit can be by
Hydraulic pump 4, overflow valve 5, two position, three-way electromagnetic change valve 6, Pressure gauge 7 and hydraulic line 8 are formed, hydraulic pump and overflow valve and
Two position, three-way electromagnetic change valve is connected by hydraulic line, and when hydraulic circuit runs, the piston rod of hydraulic cylinder is in the process of stretching out
In, promoting load simulating device, according to experiment needs, select different counterweights to load, (counterbalance mass is respectively for 3 counterweights
For 0.5kg, 1kg, 2kg) flexible combination can be needed to use according to experiment, it is achieved 0.5kg, 1kg, 1.5kg, 2kg, 2.5kg etc. 5 kinds
Load pressure, thus complete the experiment of unequally loaded hydraulic loaded.Need also dependent on teaching, by changing the group of hydraulic circuit
Become, complete the loading experiment of other Typical hydraulic circuits, such as speed control loop, pressure-control circuit, Speed changeover circuit etc..
The above, preferably detailed description of the invention the most of the present utility model, but protection domain of the present utility model is also
Being not limited to this, all those familiar with the art are in technical scope disclosed in this utility model, according to this reality
All should contain of the present utility model by novel technical scheme and design of the present utility model thereof in addition equivalent or change
Within protection domain.
